In Situ Cytokine Expression and Morphometric Evaluation of Total Collagen and Collagens Type I and Type III in Keloid Scars

Figure 2

(a) Total collagen percentage present in biopsies of patients with keloid compared with that of patients in the control group (Mann–Whitney; ). (b) Percentage of collagens types I and III present in biopsies of patients with keloid compared with that of patients in the control group. Analysis of collagen type I in patients with keloid compared with that in patients in the control group (Mann–Whitney; ). Analysis of collagen type III in patients with keloid compared with that in patients in the control group (Mann–Whitney; ). Analysis of collagen types I and III in the control group (Wilcoxon; ). Analysis of collagen types I and III in patients with keloid (Wilcoxon; ). (c) Maturation index calculated from the percentages of collagen I by III present in biopsies of patients with keloid compared with that of the control group (Mann–Whitney; ). The horizontal line represents the median, the bar percentile of 25% to 75% and the vertical line percentile of 10 to 90. (d) Correlation between the percentage of collagens type I and type III in patients with keloid compared with patients in the control group (Spearman; , ). indicates significant value.
